PRIVACY POLICY — BLUETOOTH CODEC CHANGER
Effective date: October 26, 2026
App: Bluetooth Codec Changer (com.tahatec.bluetooth_codec_changer)

SUMMARY
Bluetooth Codec Changer shows which audio codec your phone uses with your
Bluetooth headphones and speakers, and lets you change it. The app has no
accounts, no sign-in and no servers of its own: the names, addresses, battery
levels and codec settings of your Bluetooth devices are read on your device,
shown to you, and never uploaded, stored or shared by us. The network is used
only for advertising, for the optional push notifications, and for the
anonymous usage and crash reports described below.
1. INFORMATION THE APP READS ON YOUR DEVICE
- Your paired Bluetooth devices: name, the alias you gave them, device type,
connection state, battery level (where the device reports it) and the
Bluetooth profiles they support. Read from Android; no scanning for new
devices takes place.
- The audio codec in use with the connected device, the codecs the
connection can use, and the codecs your phone can encode.
The app does not use the camera, the microphone or your location, and it
never searches for nearby devices.
2. INFORMATION THE APP STORES
Only on your device: a preferred codec for each device you choose to set one
for (keyed by that device's Bluetooth address), an activity log of
connections and codec changes, and your preferences (theme, language,
re-apply setting, notification choice). Sharing a codec report is always
started by you and goes through the app you pick; the report contains no
Bluetooth address, and we never receive a copy. Uninstalling the app deletes
everything it stored.
3. ADVERTISING
The app shows ads served by Google AdMob, which may also use certified
mediation partners such as Meta Audience Network. When requesting and
showing ads, these partners may collect and process data on their own
behalf, such as your advertising ID, IP address, coarse location derived
from it, and device and diagnostic information. This is standard for
ad-supported apps and is governed by the partners' own policies:
- Google:
https://policies.google.com/technologies/partner-sites
- Meta Audience Network:
https://www.facebook.com/about/privacy
In the European Economic Area, the United Kingdom and other regulated
regions, the app shows a consent form (Google's User Messaging Platform)
before any ad request is made, and you can change your choice at any time
under Settings → Ad privacy options inside the app. You can also reset your
advertising ID or opt out of ad personalisation in your device's Google
settings.
4. USAGE ANALYTICS AND CRASH REPORTS
The app uses Google Firebase Analytics and Firebase Crashlytics to learn
which features are used (for example which codec was selected and whether
the change succeeded) and to receive reports when the app crashes. These
reports contain device and app information (model, OS version, app version,
a random installation identifier) but never a device name, an alias, a
Bluetooth address or anything you typed. Firebase's handling of this data is
described at
https://firebase.google.com/support/privacy.
5. PUSH NOTIFICATIONS
If you allow notifications, the app registers with Firebase Cloud Messaging
so we can send occasional tips and update announcements. Registration
creates a device token held by Google; it is not linked to your identity and
we store no list of recipients. You can turn notifications off at any time
in your device's app settings. The prompt is shown only after you have
used the app — after your second successful codec or connection change —
never on launch.
6. PERMISSIONS AT A GLANCE
- Nearby devices (Bluetooth connect; on Android 11 and earlier, Bluetooth):
to list your paired audio devices, read and change their codec, and
connect or disconnect them when you ask. Not used for scanning or
location.
- Internet: used by the advertising, consent form, analytics and
notifications described above. The app itself sends none of your
Bluetooth information anywhere.
- Notifications (Android 13 and later): requested only once, as described
in section 5.
7. CHILDREN
The app is an audio utility, is not directed at children under 13, and we
knowingly collect no personal information from anyone, including children.
8. DATA DELETION
We hold no data about you, so there is nothing for us to delete: uninstalling
the app removes everything it stored on your device. Analytics and crash
data are held by Firebase under the policy linked in section 4, and
advertising data by the partners in section 3.
9. CHANGES TO THIS POLICY
If this policy changes, the updated version will be published at the same
address with a new effective date. Material changes will be reflected in the
app's store listing.
